it at 31 mpg on the highway, 23 in the city and 26 combined. That is less than the naturally aspirated model with either an automatic transmission or a manual, the former of which gets 35 mpg highway, 26 in town and 29 combined. But the naturally aspirated Mazda6's 184 horsepower and 185 pound-feet of torque are well short of the turbo engine's 250 horsepower and 310 pound-feet.

As far as power is concerned, the Mazda6 is also very even with the competition, most of which makes right around 250 horsepower, though the Toyota Camry's naturally aspirated V6 is a class-leader at 301 horsepower. But the 6's advantage is in torque. None of the mainstream family sedans touch the Mazda's whopping 310 pound-feet. The 2.0-liter Honda Accord and Ford Fusion come the closest at 273 and 275 pound-feet respectively. To beat the Mazda6 would require going for the Ford Fusion Sport, which is a unique step up in the segment with a turbocharged V6 making 380 pound-feet. The Fusion Sport takes a serious hit in the fuel economy department, though, getting just 20 mpg combined.
